❓ FAQ

Frequently Asked Questions

Everything you need to know about QR codes and our generator.

Is this QR code generator completely free?
Yes. KJSynthora QR Code Generator is 100% free with no signup, no watermark, no download limits, and no hidden costs. You can generate unlimited QR codes and download them in PNG, SVG, or PDF format without paying anything.
What types of QR codes can I generate?
You can generate 8 types of QR codes: URL (website links), WiFi (network credentials), UPI (payment), WhatsApp (with pre-filled message), vCard (digital business card), Email (with subject and body), SMS (with pre-filled message), and plain Text.
Can I add a logo to my QR code?
Yes. Enter a logo image URL or upload a file using the Upload button. The logo is embedded in the center of the QR code. Use "H" (High) error correction level when adding a logo — it ensures the QR is still scannable even with part of it covered by the logo.
What is error correction level?
Error correction allows QR codes to be scanned even if part of them is damaged or covered. There are 4 levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher levels make the QR larger but more resilient. Use H when embedding a logo.
Which format should I download — PNG, SVG, or PDF?
PNG is best for digital use — websites, emails, presentations. SVG is a vector format, ideal for printing at any size without pixelation — use it for business cards, banners, and merchandise. PDF is best for document embedding.
How do I create a WiFi QR code?
Select the WiFi tab, enter your network name (SSID), password, and security type (WPA2 for most modern routers). Generate and download the QR. When guests scan it, their phone automatically connects to the WiFi network without typing the password.
Is my data sent to a server?
No. All QR code generation happens 100% in your browser. Your URLs, WiFi passwords, UPI IDs, and contact information never leave your device and are never sent to any server. This is especially important for sensitive data like passwords and payment IDs.
